I had very limited space and this sump fit perfectly. This was my first sump and I set it up, plumbed it, installed all the equipment and now everything is filtering smoothly. My only concern was shipping damage, but BRS packaged it very well and I had no surprises when I filled it up for a pre-installation pressure test! Nothing negative to say about it - Iknew how much space I had and I read all the specs on it...So it's Good!

Great for BerlinBy Ericon 7/26/2014

When i received this sump the cap was off in the overflow pipe on the first chamber. I just glued it back on and has worked great ever since. The third chamber is a little small if you are thinking about putting your skimmer in there. I run it in the second chamber with no problems the water level stays constant there, but not able to have a refugium this way.

Nice design, hit or miss on arrival damageBy John on 5/11/2014

Well I will first start off by saying that the original shipment came damaged. The damage was limited to one of the baffles only being half glued and a screw being stripped. I contacted BRS who said they would refund me or I could go through Aqueon for a replacement. I decided to go through Aqueon, which has an excellent customer service, and shipped me another unit for a replacement. When that unit arrived the intake tube was detached so I again contacted customer service who asked if I felt comfortable attaching it if they sent me the supplies. As I elected to do the repairs myself, Aqueon went ahead and sent some additional goodies as a compensation for the troubles and completing the repairs myself. Overall I am very happy with the purchase and would recommend the sump to anyone, but I would also warn them on the potential damages that may occur. Which I honestly believe that the shipping company caused all the damages. I would recommend to packing the boxes better, maybe using Styrofoam peanuts instead of the bags full of air which is capable of becoming deflated in shipment.

Not big enough By JPSon 11/22/2013

I have the 4, and it has no room for a larger skimmer and my tank is 220gl. Big mistake.

Wish I went BIGGERBy ReeferGilon 10/3/2013

I have a 75g tank and went with the model 3. One year after it's all been running, I have two major regrets. I wish I had larger stand doors and I wish I went with the Model 4. I'm running a Reef Octopus pin110 skimmer, GFO reactor, probe holder, float switch, Mag 7 return pump and ATO switch in the last stage. My last stage is soooo crampped, no space at all. The model 3 is 25.5" long while the model 4 is 36" long. Would have given me more room making it easier to clean and given me more options for a larger skimmer if I wanted to upgrade later. Other than that, I've had no issues. Chaeto is growing great under LED lights and no leaks. Runs as designed.

The sump is OK just not with a refugiumBy Sabokenon 8/18/2013

Saboken wouldn't recommend this product to a friend

For the price there should be more options to use this as a Refugium the barrier between chamber 1 & 2 has no way to lock it in place when/if the power goes out the Barrier drops and messes up the flow in my Refugium I could modify it but if I do and anything goes wrong like the first unit that was not glued together right I will be in my own since it will void the warranty if I drill it in any way, Aqueon has a great customer service they sent me a new sump in 2 days and did not want the old one back but it leaks, if I find a way to secure the wall to the Refugium I will post it, If you are looking for a Berlin or want to use the optional bio balls I am sure this would be great But I have a Green Mandarin and have been trying to keep pods in the Refugium but the flow is to high and if the wall drops most of them get pushed into chamber 3 and up to the display tank they are eaten quickly.

Great small package!By Jameson 3/25/2013

i needed a sump for both my current 60 gallon and wanted something I could expand for my next tank a 100 gallon reef. This fits in my cabinet, is flexible for either refugium or berlin style sump and its nice and quiet!

Good for a starter sumpBy Caseyon 3/6/2013

Casey would recommend this product to a friend

I purchased the Model 3 ProFlex for my first saltwater system which is a 90 gallon tank. I can say that it was good for starting out, but I added a 15 gallon tank for my refugium because I did not have enough room to have a refugium, protein skimmer, and carbon reactor in it. I would not recommend drilling it for an external pump because the plastic walls are a little too weak.

GreatBy Tomon 12/27/2012

I am very pleased with this product. It can be easily changed to fit your aquariums. It is great for reef aquariums with the advanced filtration. There is a lot of room to add a large Refugium and skimmer. You just need to buy a return pump and your ready to roll!

Makes a great sumpBy Chadon 12/15/2012

Chad would recommend this product to a friend

I am very pleased with this product. It is setup as a modular unit that can be be easily made into any popular style of pump. I got a model 2 (set up Berlin style) for my 75gal reef and couldn't be happier with it.

It is held underneath my tank in a stand compartment and holds all my goodies. Reactor in/outs, heater, ATO, and over sized skimmer.
